A note before we start. Don’t take magnesium supplements if you have kidney disease unless your doctor advises it, and check with a pharmacist if you take medication — magnesium can interact with some antibiotics and osteoporosis drugs. This article is general information, not medical advice. LifeWave X39 is a non-transdermal, general-wellness phototherapy patch that gently stimulates the skin with light to support the body’s natural energy flow for strength and stamina. It is not a treatment for any condition.
Magnesium is involved in hundreds of reactions in the body, from energy production to muscle and nerve function, and many adults eat less than recommended. Getting enough is cheap and simple.
Key takeaways
- Magnesium supports energy, muscle, nerve and heart function.
- Low intake is common, especially with processed diets.
- Stress, heavy sweating, alcohol and some medications raise needs or losses.
- Food first; supplements within the label dose if needed.
Why so many people fall short
- Processed food is low in magnesium.
- Heavy exercise and sweating increase losses.
- Alcohol increases excretion.
- Some diuretics and long-term acid reducers lower levels.
- Absorption tends to fall with age.
Possible signs of low magnesium
Muscle cramps or twitches, fatigue, poor sleep and irritability. These overlap with many other causes, so they’re not proof. A GP can check if you’re concerned.
How to get enough
Food first: leafy greens, pumpkin seeds, almonds, cashews, beans, lentils, oats, brown rice, dark chocolate, avocado and bananas.
Supplements: glycinate and citrate are well absorbed; oxide is poorly absorbed. Stick to the label dose and keep supplemental magnesium within the official upper limit (250mg a day from supplements in the EU and Ireland). Loose stools are a sign you’ve taken too much. I take magnesium before bed. See magnesium after 40 and best supplements for men over 40.

Frequently asked questions
Which form is best?
Glycinate is gentle on the stomach; citrate is well absorbed but can loosen stools.

No. No such claim is made. X39 is not intended to diagnose, treat, cure or prevent any disease.
